[asterisk-users] indications.c: Can't generate that much data!

[Dermot Bradley]

Linux 2.6.20, asterisk 1.2.23, mISDN 1_1_5, Digium B410P BRI card.

When calls come in via ISDN the destination phone does ring but the
caller hears no ringing tone, once the SIP phone is answered everything
works as expected. Calls from SIP phone to SIP phone internally do let
the caller hear a ringing tone.

With full asterisk logging enables the logs show:

correct entries in there for UK tones.
